Electrical stimulation of the spinal cord can help recover mobility in some paralysed patients. However, the mechanism underlying this partial recovery of function remains unknown. A recent human study has confirmed the involvement of a previously identified group of cells in mice, paving the way to targeted treatments.

In a recently published study in Nature, researchers modelled the electrical stimulation paradigm used in humans and called epidural electrical stimulation (EES) in mice, in which they identified the responsible cell population.
